SEWER-PIPE SECTION FOR SEWER-BUILDING.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application led October 29, 1910. Serial No. 589,794.

To all whom it may concern.' v

Be it known that I, ILIJAM H. ROOK, Jr., a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Sewer-Pipe Sections for Sewer-Building, of which the following is a specification.

This invention relates to improvements in the construction of segmental sections of vitriied sewer-pipe for use in building large conduits such aspsewers, etc., and the object is to provide a section which when properly assembled with other similar sections may be used for forming a sewer or other tubular conduit. It is contemplated that these sections will be laid up in annular formation to form the wall of a sewer of greater diaineter than can be constructed ofthe ordinary cylindrical sections of sewer-pipe.

A principal object of this invention is to so construct the various segmental sections that each will be provided with superior interlocking means whereby' they are securely held in position when laid, said means embodying the formation at the ends of each section of transverse shoulders to cooperate with the shoulders of al'mttjng,r sections to constitute a space .for the mortar by which the sections are 'joined together, the shoulders atl'mdxngA a backing or abutment for the ccmenting vehicle used.

With the foregoing and other objects in view, the invention consists iu the novel` construction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accomtmnying drawings which form apart hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and n'ioditications canhc resorted to which come within the scope of the claims hereunto appended.

In the drawings, in which similar refer ence numerals indicate like parts in the different figures: Figure '1 is van end elevation.

partly in section of a portion of a sewer or tubular conduit constructed of sections embodying this invention. liig;v 2 is a view in side elevation of two sections arranged in abuttingrelation; and, Fig. 3 a }j c1.s}icctive 'view of a Sewer-pipe-'section cmbodyiiu.;` (his invent-ion. I

Before going into a detailed discription 0f this invention it will be stated that these sections are preferably formed of vitriied sewer-pipe and arranged ,when properly assembled to ,form the wall of a tubular sewer or conduit and as all of the sections are constructed precisely alike, it is thought` that a description of one, together with the description of the manner of assembling ya plurality of such sections, will be sufficient.

It will be apparent in laying up the various sections in constructing a tubular conduit or sewer, it will be after the manner in which brick are commonly laid; that is to walls 4 and 5. The outerwall l and, inner wall 3 arev concentric with the center of the sewer or conduit in which they are to be employed and are preferably .made integral with the lateral Walls 4 and 5. The lateral Wall Il is provided with a longitudinally-extending dove-tailed groove 6 and the wall 5 with a corresponding longitudinally-extending' rib 7. The `groove 6 is preferably made sligl'itly larger 'than the rib 7, so that when two similarly-const-rueted sections are laid in lateral lapping engagement, the rib 7 of one section will be freely received in the groove G of the .complementary section and leave sullicieut. space for the insertion of a binding clement, such as mortar. lhe outer faces of the lateral walls et and 5 are, preferably radial with respect to the cento) of the sewer or conduit in which they are used. Each section is further provided with an approximately central radial.' web S extend ing from the inner face of the outer wall 2 to the outer face of the inner wall 3. `Each section is also provided with two webs i) and 10 arranged parallel and in spaced relation and extending between the lateral walls 4- and 5, the space between the webs 9' and l0 being interrupted by the een tral radial. web 8, all of which webs extend from ond to end of each section... v

At one. end of cach section the inner half of the Section is cu( away to provide a shoulder 1l, so that the outer portion overhangs the lower portion, and this shoulder is customarily provided alone` the line, of the inner face ol' tho web 9, and the opposite cud of each .section is cut away at its outer pou tion to provide a shoulder l2, said shoulder being usually located at a point approximately along the outer face of the inner web l0, so that when complementary sections are abutted end to end there will exist a Space between the shoulders 1l and l2 for the reception of mortar or some equivalent binding material, this oocurring at all times when the outer surfaces of abutting sections are in alinement, as shown in Fig. 2, the space between theshoulders 1l and l2 for the reception of the mortar being designated in the drawings by the reference numeral 13, the inner face of the web 9 constituting the shoulder l1 and the outer face of the web 10 constituting the shoulder l2 forming suitable abutments or backings against which a binding element such as mortar may engage for locking the abutting ends of the sections together when being set. up. l v

In assembling segments constructed in accordance with the foregoing description for the building oi a tubular conduit or sewer, the lateral walls 1l and 5 are preferably covered with mortar or equivalent material for uniting them in annular formation, permitting the longitudinal rib 7 to enter the complementary groove 6 of adjacent sections and be intel-locked .therewith through the medium of said mortar, the mortar being designated in the drawings by the reference numeral l-l.

In manufacturing these sections they are preferably formed 1n a press Aand afterward the cutting away of portions at the ends o' the sections is performed by hand, although the method of manufacturin these sections is immaterial to this invention, as long as said sections embody I'neans on the lateral walls thereof for c using the locking of adj acent sections and he provision at the ends of said sections of overlapping portions to provide spaces for the reception of a binding element, with the abutting ends provided with transversely-extending shouiders constituting an abutment or backing for said binding element.

I clainu' l. A hollow tile having its inner wall cutaway at one end and its outer wall cut-away at the other end to form shoulders reversely arranged at opposite ends, the ,shoulders when two tiles. abut overlapping'and out'of contact to form a transverse mortar groove, a longitudinal wall terminating near the transverse groove at each end whereby a communicating chamber opening into Y the mortar groove is formed to provide a mortar clench.

2. A hollow tile. having its inner wall cutaway at one end an its outer wall cut-away 'at the other end to rm shoulders reve'rsely arranged at opposite ends, the shoulders Wilen two tiles abut overlapping and out of contact to form a transverse mortar groove, spaced longitudinaily-extending walls terminating near the transverse groove at each end to provide an lopening communicating with said grooves to constitute a space for a mortar clench.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
